Improvement in valve arrangements for hose



UNITED STATES PATENT OFFICE- ROBERT A. PARRISH, JR., OF PHILADELPHA,PENNSYLVANIA.

lMPROVEMENT IN VALVE ARRANGEMENTS FOR HOSE.

Specification forming part of Letters Patent No. 44,743, dated October1S, 1864; antcdated December l2, 1563.

To all whom it may concern:

Be it known that l, ROBERT A. PARRIsII, Jr., of' the city and county ofPhiladelphia, and State of Pennsylvania, have invented a new andImproved Automatic Tater-Lock, of which the following is a full andexact description, reference being had to the accompanying dra-wing, andto the letters or" reference marked thereon.

The nature ot' my invention consists in introducing into the end of apeifectlystraightened piece of hose, (as shown at A in the drawingannexed,) a metallic pipe, marked B, about nine inches long, ofthe usualbore of garden branch pipes, and truncated at the inner extremity at anangle of fortyiive degrees, the slope of said truncation inclining`(when the pipe is in situ) downward and for ward, (as indicated in thedrawings at 0,) at which point the diameter ofthe pipe should be halt'that of the interior diameter of the hose itself. 'the pipe, placed laton the side ofthe hose, should be surrounded by water-tight packing`from the nozzle to the distance of about halt' its length, (as shown inthe drawing by the parts marked 1),) whereby the inner halt' of the pipeis left free.

The truncated extremity of the pipe must be adjusted in precise contactwith an elastic partition or valve of gutta-percha, or other substance,(in the drawing shown at E,) which, attached by its periphery to thehose transversely and sloping parallel with the truncation, closes upthe orice of the pipe, and also permanently closes one-half ot' thediameter of the hose. An external, mark at F (as indicated in thedrawing) shows where the hand of the operator grasps the hose.

Vhile the hose is kept straight the pressure of the current of waterjams the partition against the truncated end of the pipe and stops theflow of water. When, however, the hose is bent into the curve, which,from its elasticity and weight it usually assumes while 'in use, (asdefined by the dotted lines in t-l e drawings,) the partition or valvevretreats below the extremity ofthe pipe and lets the water through.

When the hose is thrown on the ground, it straightens by its ownelasticity, and the aperture in the branch pipe closes automatically.

that I claim as my invention, and desire to secure by Letters Patent,is-

l. The employment of the curvilinear ilexure and elasticity of hose as aleverage for opening and closing the branch pipe by the agency of anypartition or valve, in the manner above described.

2. 1n combination therewith, the truncation, adjustment, and packmg otthe branch pipe for about half its length with water-tight packing, asabove set forth.
